Not a pocket watch, but just dug out an old Ladies Rolex (marked Rolex 15 j on the ratchet wheel) The dial is that of a jeweler in Victoria, B. C., Shortt Hill & Duncan. By the design I am guessing that it was made shortly after 1908 when the name Rolex came into being.
I have been threatening to look into its history for years and now I am going to try. It runs, but needs cleaning; I also have to look for a Canadian watchmaker who will take it on.
